Bodyfitter Index

Tactilus - Request a Demo

Our proprietary Bodyfitter® algorithm allows the retailer or manufacturer of mattresses the ability to produce a scientifically derived value that is highly correlated to the support and comfort that the customer will experience. Bodyfitter®, collects pressure distribution and magnitude data from two discrete sections of the body, the lumbar region and buttocks region and though a sophisticated series of computations produces a singular output or ergonomic index.

From years of research gathered from thousands of individuals on various sleep surfaces, we’ve compiled a database that is at the core of the Bodyfitter® algorithm. Sensor Products Inc. offers our Bodyfitter® sensor system and analysis package with the intention of enabling the consumer to purchase a truly well fitted mattress. Customers will leave with the assurance of a scientifically validated mattress decision, minimizing post-purchase dissonance, and will associate your name with the progressive use of science and technology.

"What Bodyfitter® does is attempt to align the subjective perception a customer develops when lying on a mattress with hard science. If these two factors are congruent, post purchase dissonance is highly reduced and thus returns are greatly minimized." — Jeffrey G. Stark, CEO


  • Most economical technique to capture mattress “fit” data
  • Introduces scientific validity to the mattress selection process
